     CLASSIFIER = <span class="helptopic">prtClassKnn</span> returns a K-nearest neighbors classifier
 
     CLASSIFIER = <span class="helptopic">prtClassKnn</span>(PROPERTY1, VALUE1, ...) constructs a
     <span class="helptopic">prtClassKnn</span> object CLASSIFIER with properties as specified by
     PROPERTY/VALUE pairs.
 
     A <span class="helptopic">prtClassKnn</span> object inherits all properties from the abstract class
     prtClass. In addition is has the following properties:
 
     k                  - The number of neigbors to be considered
     distanceFunction   - The function to be used to compute the
                          distance from samples to cluster centers. 
                          It must be a function handle of the form:
                          @(x1,x2)distFun(x1,x2). Most prtDistance*
                          functions will work.
 
     For information on the  K-nearest neighbors classifier algorithm, please
     refer to the following URL:
 
     <a href="http://en.wikipedia.org/wiki/K-nearest_neighbor_algorithm">http://en.wikipedia.org/wiki/K-nearest_neighbor_algorithm</a>    
 
     A <span class="helptopic">prtClassKnn</span> object inherits the TRAIN, RUN, CROSSVALIDATE and
     KFOLDS methods from prtAction. It also inherits the PLOT method
     from prtClass.
 
     Example:
 
      TestDataSet = prtDataGenUnimodal;      % Create some test and 
      TrainingDataSet = prtDataGenUnimodal;  % training data
      classifier = <span class="helptopic">prtClassKnn</span>;           % Create a classifier
      classifier = classifier.train(TrainingDataSet);    % Train
      classified = run(classifier, TestDataSet);         % Test
      classifier.plot;</pre></div><!--after help --><!--seeAlso--><div class="footerlinktitle">See also</div><div class="footerlink"> <a href="./../prtClass.html">prtClass</a>, <a href="./../prtClassLogisticDiscriminant.html">prtClassLogisticDiscriminant</a>, <a href="./../prtClassBagging.html">prtClassBagging</a>,
